The Android 6.0.1 Marshmallow-based CyanogenMod CM13 custom ROM has been made available to Samsung's 2014 flagship phablet Galaxy Note 4.

It weighs around 316MB in size and comes with Marshmallow goodies such as Doze power optimisation, support for more international dialects, silent mode, the latest security patch, performance tweaks, shortcuts for key settings options and many more value-added features to enhance the user experience.

Make sure the device is rooted before going forward for custom ROM installation

Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.

Make sure the PC has USB driver software, or else the device (Galaxy Note 4) will not be recognised by the computer.

Make sure the device has more than 80% battery, or else there is chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.

Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM]

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked.
